Hi,
I have A4 B7 Cab fitted with a 3.0 V6 TDI ASB engine which has done 86k miles, and I have been having some issues with white exhaust smoke when idling, and the engine "shuddering" at idle. I have read up on these symptoms which has made me suspect the injectors, after analysing MVB 72-77 on VCDS, it was confirmed that I had three suspect injectors.
Audi recommend to replace all six items (in the region of £2900 fitted ).
I have spoken to an Audi mechanic and he assures me that these Piezo injectors can be re-conditioned, so I,m looking at removing the three faulty injectors for refurbishing.
I have a couple of questions that I,m hoping someone can answer.
Would it be wise to get all six injectors reconditioned as they have all done the same mileage, or just limit it to the three faulty ones, or do you think they will require all six anyway to "balance" them so to speak.
Which MVB represents which injector, is it mvb 72=cylinder 1, mvb 73=cylinder 2 through to mvb 77=cylinder 6, can anyone confirm this?
Also does anyone know which is cylinder 1 on the engine?
Any help would be greatly appreciated.
